Dynamic measurements with hundreds of
acquisition channels can be performed efficiently
with Siemens Simcenter Testing Solutions.
AEROSPACETESTINGINTERNATIONAL.COM // JUNE 77
Aerospace applications typically require
the acquisition and processing of
massive amounts of test data. The use of
several hundreds of sensors to measure
vibration, acoustic, thermal or any other
dynamic parameter is necessary to gain
better insights into the dynamic response of
aerospace structures and to validate their
design without missing any hidden flaws.
Such large-scale test campaigns can be a
challenge for engineers. Siemens PLM
Software has implemented several advanced
technologies to support test engineers in
large-scale test campaigns.
During the development cycle of a full
aircraft, spacecraft or component, dynamic
tests must be performed to confirm
predictions from simulations, validate the
design for certification or qualification and to
help troubleshoot issues. The measurement
system used during this process needs to
offer flexibility to cover the test requirements,
support multiple applications and make use
of the widest variety of sensors.
The Simcenter SCADAS hardware and
Testlab software are suitable for multiphysics
applications, including noise,
vibration and durability and provide
integrated signal conditioning capabilities to
support any kind of sensor. The system can
handle all acoustic, vibration and durability
test requests and can adapt to late-changes
in instrumentation and test planning.
The modular design of the Simcenter
SCADAS hardware allows the scaling of the
measurement system to the test. Independent
SCADAS frames can be mixed and matched to
assemble a large channel-count system, with
perfect synchronization between channels.
Distributing systems becomes possible and
enables easy set-up and improved accuracy
by minimizing sensor cable length.
Instrumentation of the tested item
happens at the beginning of the test
campaign and must match the test
during or after the test, providing feedback on
measurement quality and the confirmation of
the validity of the results on-the-spot. It also
allows engineers to make the best use of
testing time by testing what is really needed.
Simcenter Testing solutions combine
accurate and reliable data acquisition with
processing algorithms to methodically
manage data, provide physical insights and
enable smarter performance engineering. The
Simcenter SCADAS Hardware and Simcenter
Testlab Software successfully combines
the latest technologies to perform large
channel-count dynamic measurements
accurately and efficiently. \\

requirements and ensure accuracy. The
Simcenter Testlab Instrumentation App,
installed on any mobile device, lets the
engineer move around the structure while
controlling the acquisition software to define
the sensor parameters, document the set-up
and take pictures of each sensor.
Once the measurement set-up has been
verified, data is streamed at high speed from
the acquisition systems to the host computer.
Siemens PLM Software provides a dedicated
architecture to safely handle high-data
streams with virtually unlimited channel
counts. By using multiple recording systems
in parallel, controlled by a central operator
station, data is safely recorded and
backed-up with no single point of failure.
In case of satellite vibration qualification
testing, selected measurement points are
typically used by a closed-loop controller to
ensure that the excitation signal exactly
matches the test specifications. The potential
to acquire hundreds of channels in the
Simcenter measurement system in full
synchronization with the control system
maximizes the safety of such sensitive tests.
Online and offline data validation
capabilities allow processing of the data
